Marcono1234 updated MNG-7058:
-----------------------------
Description:
Possibly related to MNG-6420 and MNGSITE-387
The Maven [Version Order
Specification|https://maven.apache.org/pom.html#version-order-specification]
says:
{quote}
Non-numeric ("qualifiers") tokens have the alphabetical order, except for the
following tokens which come first in this order:
"alpha" < "beta" < "milestone" < "rc" = "cr" < "snapshot" < "" = "final" = "ga"
< "sp"
{quote}
It appears the intention of the author was that no qualifier ({{""}}) as well
as {{"final"}} and {{"ga"}} represent a _release_.
However, because due to this exception these qualifiers always come first it
conflicts with [SemVer 1.0.0
§4|https://semver.org/spec/v1.0.0.html#spec-item-4] defining pre-releases:
{quote}
A pre-release version number MAY be denoted by appending an arbitrary string
immediately following the patch version and a dash.
{quote}
This can result in situations where a release would come before a pre-release.
Imagine someone calls their pre-releases _alpha_, _beta_ and _gamma_. Version
_1.2.0-gamma_ is according to SemVer a pre-release, yet if a release _1.2.0_
(or _1.2.0-final_) is released, Maven considers the pre-release newer than the
release:
{code}
java -jar .\maven-artifact-3.6.2.jar 1.2.0 1.2.0-gamma
{code}
{code:title=Output}
1. 1.2.0 == 1.2
1.2.0 < 1.2.0-gamma
2. 1.2.0-gamma == 1.2-gamma
{code}
This could be solve by specifying that an empty string ({{""}}) = {{"final"}} =
{{"ga"}} < {{"sp"}} always come after any other qualifier. However, that might
be a breaking change.
